VALVE FOR WASTE PIPES OR TUBES.

Specification of Letters Patent.

' Patented Feb. 9, 1215.

Application filed January 16, 1914. Serial No. 812,425.

To all whom it may concern Be it known that I, Or'ro G. I-Irronooon, acitizen of the United States, residing at Erie, in the county of Erie,State of Pennsylvania, have invented new and useful Improvements inValves for Waste Pipes or Tubes, of which the following is aspecification.

My invention relates to means for opening and closing the waste pipes ortubes for stop and other cocks or valves, and has for its object toprovide certain improvements in the same as will be hereinafter moredefinitely pointed out and claimed, reference being had to theaccompanying drawing, in which:

Figure 1 is a side elevation of a stop cook or valve with my improvedwaste pipe and closure applied thereto, said cook or valve being shownpartly broken away. Fig. 2 is an enlarged'detail longitudinal sectionalview of my improved waste pipe and closure.

Similar numerals of reference denote corresponding parts in the twoviews.

In the said drawing the reference numeral 1 denotes the body or casingof an ordinary stop cook or valve, the same being provided with theusual valve stem 2 and hand wheel 3 for manipulating the valve thereof,and into the bonnet piece 4: of which is screwed the end of a waste pipeor tube 5. Said pipe or tube 5 communicates with a chamber 6 formed inthe bonnet piece 4:, which in turn communicates in any suitable mannerwith the valve casing 1 on one side of its valve, preferably through aduct in the valve stem 2 which will be sealed automatically by theopening of the valve of casing 1, as is common in valves of this type.Said pipe or tube 5 is screw threaded intermediate its length at 7 toreceive the inner end of a nozzle 8, the extreme outer end 9 of saidpipe or tube 5 beyond its screw threaded portion 7 being beveled on itsinner surface at 10 to form a valve seat. The nozzle 8 is formedinteriorly into a cone-shaped valve 11 adapted to seat in valve seat 10and close the same when said nozzle is screwed to position on the pipeor tube 5.

The nozzle 8 is bored diagonally of its length at 12, said borebeginning centrally of the nozzle at its outer end and extendingdiagonally inward and terminating at one side of the cone-shaped valve11, but communicating with a narrow annular chamber 13 formed betweenthe outer end 9 of the pipe or tube 5 and'the inner wall of the screwthreaded inner end of said nozzle. In operation when the parts are inthe position shown in Fig. 2 the valve 11 will be seated upon the valveseat 10, thus effectually closing the pipe or tube 5 against discharge.To open the same it is necessary only to unscrew said nozzle 8, whichwill unseat immediately the valve 11 and will permit the escape of fluidthrough pipe or tube 5 and bore 12, the rate of flow being governed bythe distance that said nozzle is unscrewed.

Having thus described my invention, what I claim as new and desire tosecure by, Letters Patent is:

1. In a device of the class described, a waste pipe or tube, a nozzle inadjustable engagement therewith and formed with an internal annularchamber surrounding the end of said waste pipe or tube, said nozzlehaving a straight bore extending diagonally therethrough andcommunicating at its inner end with said annular chamber, and a valveand valve seat in said nozzle and pipe or tube, whereby the unseating ofsaid valve from its seat will afford communication from said pipe ortube to said annular chamber and said diagonal bore.

2. In a device of the character described, a waste pipe or tube formingat its outer end a valve seat, and exteriorly screw threadedintermediate its length, a nozzle interiorly screw threaded at its innerend adjustably to engage said pipe or tube, and a conical valve in theinterior of said nozzle adapted to register with said valve seat in saidpipe or tube to close the same when the parts are screwed to position,said nozzle being provided with a straight longitudinal bore diagonallydisposed and terminating at its inner end to one side of said valve inposition to communicate with the interior of said pipe or tube when saidvalve is unseated.

3. In a device of the class described, a waste pipe or tube having aconical valve seat formed in its outer end and eXteriorly screw threadedintermediate its length, a nozzle interiorly screw threaded at its innerend adjustably to engage said pipe or tube, and a conical valve in theinterior of said. nozzle adapted to seat in and close said valve seat insaid pipe or tube when the In testimony whereof, I have hereunto setparts are screwed to position, said nozzle my hand in the presence oftwo subscribing 10 leingdprovidlefl \Zith a straight longitudinalwitnesses.
